To improve our sensor noise estimate, the ACC cables should be clamped using a rubber pad and a big dog clamp on the SP tabletop before exiting the table. Also the sensors themselves should be covered with a foam box or a double cardboard box. The high-frequency acoustic noise may limit the 10 Hz performance since piezos are not very linear.
I've set up the Wilcoxen accelerometers on the SP table for a huddle test, to estimate their noise levels.
They're clamped down to the table along the same axis, and their housings are in good contact, in hopes to make them as correlated as possible.
Wilcoxon. Not Wilconox or Wilco or Wilcoxen. Have some pity on future keyword searchers.
